While Apple may tinker with the final packaging and design of the final phone, it's clear that the features in this lost-and-found next-generation iPhone are drastically new and drastically different from what came before. Here's the detailed list of our findings:

What's new

• Front-facing video chat camera • Improved regular back-camera (the lens is quite noticeably larger than the iPhone 3GS) • Camera flash • Micro-SIM instead of standard SIM (like the iPad) • Improved display. It's unclear if it's the 960x460 display thrown around before—it certainly looks like it, with the "Connect to iTunes" screen displaying much higher resolution than on a 3GS. • What looks to be a secondary mic for noise cancellation, at the top, next to the headphone jack • Split buttons for volume • Power, mute, and volume buttons are all metallic

What's changed

• The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic in order for the cell signal to poke through. Tapping on the back makes a more hollow and higher pitched sound compared to tapping on the glass on the front/screen, but that could just be the orientation of components inside making for a different sound • An aluminum border going completely around the outside • Slightly smaller screen than the 3GS (but seemingly higher resolution) • Everything is more squared off • 3 grams heavier • 16% Larger battery • Internals components are shrunken, miniaturized and reduced to make room for the larger battery
